Community Update: July 2, 2018

As we begin July, we will continue our regular updates on Stony Hollow, our progress and any new information available as we move forward.

Our site activities continue to focus on monitoring and inspection programs, assuring the extensive control systems now in place continue to function well. We continue to maintain gas collection systems and the odor control improvements made with the installation of the cover shown below.

We have begun our routine gas well installation and it is going well. More information follows on all planned activities.

Action Updates:

Synthetic Cap and Gas Well Collection System Employed:  The synthetic cap and gas well collection system continues to function and perform well.  This system continues to control odors and proactively address future issues. We routinely inspect the area to assure its continued effectiveness.   Our site gas technicians are on site for daily inspections to ensure all wells are operating properly and the vacuum is being applied. Gas well monitoring and tuning of the well field continues.

2018 Gas Well Installation:  We began additional gas well installation along the northwest and western slopes, away from the capped area. This routine installation is part of general landfill maintenance. We are employing odor control protocols, currently including no drilling activity during the weekends and any holidays. Weekly construction updates are provided to our local regulatory agencies and district partners during the construction. We also will provide more routine updates and any odor alert notification if we expect to have any off-site odors. The photograph below is of the drill rig installing a vertical gas well.

Odor Surveillance: Odor surveillance continues three times a day, seven days a week. Results are maintained on site and available for agency inspection. Since activating the cap, the third-party consultant has continued to report a decrease in intensity and scope of odors in the daily odor surveys.  As we continue any site maintenance and gas well installation work, we will issue potential odor alert notifications when we expect the potential for off-site odors.

Odor Management Plan: The Ohio EPA sets clear guidelines and measurement criteria that must be met before they will give approval for any changes. We continue to operate in accordance with the plans outlined in the agency order.
